January 15, 2012, Novi, Michigan, USA – Kistler North America (www.kistler.com), a worldwide supplier of precision sensors, systems and instrumentation for the dynamic measurement of pressure, force, torque and acceleration, has introduced a new family of single axis and triaxial lightweight, miniature PiezoBeam® IEPE accelerometers with optional TEDS, designed for the multi-channel modal and structural analysis of small or thin-walled structures, components and subsystems, as well as full vehicle testing within automotive, aerospace, commercial aviation and general laboratory testing environments.
The single axis Kistler Type 8640A is the company’s dimensionally smallest, lowest mass PiezoBeam® IEPE accelerometer model, weighing just 3.5 grams. Offered in ranges of ±5 g, ±10 g and ±50 g with sensitivities from 1000 mV/g to 100 mV/g, the sensor’s ceramic cantilever beam sensing element is thermally compensated using patented methods that allow it to emit an electrical charge proportional to vibration (World patent number W0/2007/062532; European Patent: 2006790940; U.S. patent number 12,088,325). The sensing element is enclosed within a hermetically sealed, welded titanium housing with low base strain sensitivity. An internal low noise charge amplifier provides a low impedance output with outstanding amplitude and phase response over a wide frequency range and exceptional measurement stability. The single axis Kistler Type 8640A also features an integral 10-32 connector, as well as several mounting accessories, for easy installation into space constrained environments.
For simultaneous vibration measurements in three orthogonal axes, Kistler offers the Type 8688A precision PiezoBeam® IEPE triaxial modal accelerometer. The Kistler Type 8688A is the company’s dimensionally smallest, lowest mass PiezoBeam® IEPE triaxial accelerometer model, weighing just 6.7 grams (for 1000 mV/g). Available in ranges of ±5 g, ±10 g and ±50 g, with choice of 1000 mV/g, 500 mV/g or 100 mV/g sensitivities, the globally patented Type 8688A (U.S. patent number 12,088,325) incorporates Kistler PiezoBeam® technology, with the ceramic cantilever beam sensing element enclosed within a lightweight, robust, welded titanium housing. Sensing elements are designed to provide outstanding amplitude and phase response over a wide frequency range and are temperature compensated using Kistler’s own patented methods. Type 8688A sensors feature an integral low-noise charge amplifier that converts the charge signal to a proportional high level voltage signal. In addition, Kistler Type 8688A triaxial accelerometers offer an industry standard 4-pin, ¼-28 connector, as well as several mounting accessories, facilitating easy installation into space confined areas, with the ability to mount the sensor on any of its three faces.
Both single axis and triaxial models operate directly from an IEPE power source found in most FFT analyzers, as well as from Kistler Piezotron® power supply couplers or any other industry standard IEPE-compatible power source. Units are ground isolated when mounted with the optional twist-clip or adhesive adapter.
